How To Install dump on CentOS 8
Introduction
In this tutorial we learn how to install dump on CentOS 8.
What is dump
The dump package contains both dump and restore. Dump examines files in a filesystem, determines which ones need to be backed up, and copies those files to a specified disk, tape, or other storage medium. The restore command performs the inverse function of dump; it can restore a full backup of a filesystem. Subsequent incremental backups can then be layered on top of the full backup. Single files and directory subtrees may also be restored from full or partial backups. Install dump if you need a system for both backing up filesystems and restoring filesystems after backups.
We can use yum or dnf to install dump on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install dump.
